[Problems to be Solved by the Invention] In such a conventional method for attaching a Chianti structure, the Chianti structure is supported in a cantilever manner, and the position of the positioning pin on which the Chianti structure is supported and the position of the Chianti structure are determined. Since the position of the center of gravity is shifted horizontally from the position of the center of gravity of When an object is actually attached to a building, the attitude of the Chianti structure must be maintained in an upright state, which poses a problem in that the work of attaching the Chianti structure becomes complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for installing a Chianti structure that facilitates the installation work.

[0005]

[Means for Solving the Problems] The present invention positions the insertion hole of the bracket of a Chianti structure on the indoor side of the center of gravity of the Chianti structure, and inserts a positioning pin on the building side into this insertion hole. The weight of the Chianti structure is supported by the building, and the Chianti structure is mounted around the positioning pin using a temporary fixing jig that is provided on either the Chianti structure or the building and engages with the other. After temporarily fixing the Chianti structure in an outwardly inclined state, the Chianti structure is moved to the positioning pin by moving a pulling member provided at one end of the temporary fixing jig and movable along the longitudinal direction of the temporary fixing jig. The structure is characterized in that the Chianti structure is brought into an upright state by being raised toward the building side, and in this state, the Chianti structure is connected to the side wall using a coupling tool for final installation.

[0006]

[Operation] According to the present invention, the Chianti structure is temporarily fixed in an inclined state using a temporary fixing jig, and the Chianti structure is raised to an upright state using a pulling member provided on the temporary fixing jig to perform the installation work. It will be done. Here, since the falling moment due to the Chianti structure's own weight is absorbed by the pulling member, the Chianti structure is automatically held in an upright state, making it unnecessary to separately hold the Chianti structure, and connecting work using a coupling tool. etc. become easier.
